Jodi says the lessons of her past-life regression were put to the test almost immediately when she watched the episode of The Oprah Show that featured an Osmond family reunion. During the show, Marie Osmond presented Oprah with a gift—a one-of-a-kind doll of Oprah as a child.

"My instinct says to me, 'Flee. Turn it off.' Because that's what I would have done in the past," Jodi says. "[Instead] I immediately thought of the light and I heard my grandfather's voice say, 'It's okay.' &38230; Before, there's no way I could have watched that show, absolutely no way."

While one in five Americans say they believe in reincarnation, Dr. Oz wonders if what Dr. Weiss calls past-life regression might be something else. Are the people he treats really reliving memories from lives they have lived before?

"When symptoms disappear, that's usually not from imagination or something like that. It's usually from the real memory, the experience," Dr. Weiss says. "Imagination doesn't cure symptoms."
